1. A method comprising:
identifying a plurality of images corresponding to sky conditions;
isolating cloud pixels from sky pixels in each of the plurality of images, wherein the isolating of the cloud pixels from the sky pixels comprises determining a cloud mask that is a binary segmentation mask and comprises the cloud pixels in a first color and the sky pixels in a second color that is different from the first color;
responsive to determining percentage of cloud pixels in one or more of the plurality of images meets a threshold value, determining predicted cloud movement relative to sun position; and
causing a tint level of an electrochromic device to be controlled based on the predicted cloud movement relative to the sun position.
